yeah i know i saw that video but i meant like the crankcase?Like i saw some videos on youtube and they heated up the crankcase and then they put it together,unlike you you didn't have to heat up nothing cuz it's a different job i'm guessing?..Are they called the main bearings?

I have a Stihl 036 PRO that a friend has asked me to do a top end replacement on. The aftermarket cylinder does not have the stud on top that the cover secures to. Do you usually use the one from the old top end or just purchase a new one? I don't see how to remove the old one or install a new one. Do you have any experience with these?

The rubber intake boot is easily re-installed with a loop of nylon cord wrapped around the tube and threaded through the provided hole and tugged through the rear plate. It will cinch closed as it pulls thru with ease. It also helps keep the pumper hose from detaching.
